Steps to reproduce:

Attempt to view svg image (WARNING: PREPARE TO KILL FIREFOX BEFORE CLICKING LINK) http://imgh.us/slow_1.svg


Actual results:

Browser consumed all memory. System became unresponsive and had to be rebooted.


Expected results:

Either the image should be rendered with reasonable resources (for example by caching defs in a raster format) or an error should be displayed that the nesting level of defs is too deep.
